m68hc11.md (SOFT_TMP_REGNUM): Define.

Browse Source 
* config/m68hc11/m68hc11.md (SOFT_TMP_REGNUM): Define.
	(SOFT_XY_REGNUM): Define.
	(cmp split): Use the above instead of hard coded numbers.
	(8-bit op split): No need to check the mode; allow Q_REG.
	(ashift split): Adjust the first operand if it uses the SP and we
	are pushing the shifted value.
	(plus shift split): Fix when a source is in register D+X.
	("doloop_end"): Pass dummy arguments to gen_rtx_NE.
